Ask HN: Recommended Project Management Introduction

As a technical lead, I'm not a project manager but I'm working with them and I am increasingly exposed to project scheduling, costs, risk management, etc. My background is completely technical (BS Math+Physics, PhD Engineering: I work in mathematical software and HPC), but I'd like to learn more so I can be conversant with PMs and understand how they view the world. I'm a voracious reader but I would also be interested in MOOCs, online resources, etc. Anything that can give a perspective on managing and leading large scale projects with complicated interdepedencies.
